scully-plugin-minify-html

This postRenderer plugin for Scully will minify the HTML of your prerendered pages. Removing unnecessary code will decrease the size of your files.

This will speed up your loading times and mobile scores even more!

Installation

To install this library with npm run

$ npm install scully-plugin-minify-html --save-dev

or with yarn

$ yarn add scully-plugin-minify-html

This package depends on the html-minifier package. It will be installed automatically when installing this package.

Usage

Import and add the plugin to the defaultPostRenderers to execute it on all rendered pages or use the postRenderers on a route configuration to execute it for a specific route:

const {RouteTypes} = require('@scullyio/scully');
const {MinifyHtml} = require('scully-plugin-minify-html');
 
const postRenderers = [MinifyHtml];
 
exports.config = {
  projectRoot: './src/app',
  defaultPostRenderers: postRenderers,  // for all routes
  routes: {
    '/blog/:slug': {
      type: RouteTypes.contentFolder,
      slug: {
        folder: "./blog"
      },
      postRenderers: postRenderers      // per route config
    },
  }
};

Now build your app and then just run the Scully command.

npm run build --prod
npm run scully

Configuring the html-minifier options

The MinifyHtml plugin uses html-minifier under the hood, so we can configure the minify options that are being used. The available options can be found in the interface Options

The default configuration is currently set at:

import { Options } from 'html-minifier';
 
const defaultMinifyOptions: Options = {
  caseSensitive: true,
  removeComments: true,
  collapseWhitespace: true,
  collapseBooleanAttributes: true,
  removeRedundantAttributes: true,
  useShortDoctype: true,
  removeEmptyAttributes: true,
  minifyCSS: true,
  minifyJS: true,
  removeScriptTypeAttributes: true,
  removeStyleLinkTypeAttributes: true,
  // don't remove attribute quotes, not all social media platforms can parse this over-optimization
  removeAttributeQuotes: false,
  // don't remove optional tags, like the head, not all social media platforms can parse this over-optimization
  removeOptionalTags: false,
};

Configuring the options can be done on the Scully config root level, for the defaultPostRenderers or at route config level for the postRenderers.

If you don't provide options at the route level, the configuration from the root level will be used.

const {RouteTypes} = require('@scullyio/scully');
const {MinifyHtml} = require('scully-plugin-minify-html');
 
const postRenderers = [MinifyHtml];
 
const minifyHtmlOptions = {
  removeComments: false
};
 
exports.config = {
  projectRoot: './src/app',
  defaultPostRenderers: postRenderers,
  minifyHtmlOptions,    // for all routes
  routes: {
    '/blog/:slug': {
      type: RouteTypes.contentFolder,
      slug: {
        folder: "./blog"
      },
      postRenderers: postRenderers,
      minifyHtmlOptions,    // per route config
    },
  }
};
